The exact cause is not fully understood, but several factors may contribute:
- Retrograde menstruation, where menstrual blood flows backward through the fallopian tubes
- Genetic predisposition, as it can run in families
- Immune system dysfunction, affecting how the body responds to endometrial tissue
- Hormonal factors, particularly the influence of estrogen
These factors can lead to inflammation, scar tissue, and adhesions, which may affect fertility. Early diagnosis and personalised management can help protect reproductive health.
